The discharge through a small rectangular orifice is given by (where Cd = Coefficient of discharge for the orifice, a = Cross-sectional area of the orifice, h = Height of the liquid above the centre of the orifice)

Q = (3Cd × a)/√(2h)

Q = Cd × a × 2gh

Q = (2/3). Cd × a × h

Q = (Cd × a)/√(2gh)

Q = (3Cd × a)/√(2h)

Q = Cd × a × 2gh

Q = (2/3). Cd × a × h

Q = (Cd × a)/√(2gh)
